JERSEY, A CORPORATION OF NEW WORK SUPPORT.

Application lllfid December 24, 1919. tierial No. 347,185.

This invention relates to work supports and more particularly to Work supports fol machines having operating instrumentalities for performing successive operations upon 5 the Work. In the illustrated embodiment of the invention herein shown the construction of the Work support is Well adapted for use with lasting machines of the hand method ftype, an example of which is disclosed in 1 United States Letters Patent No. 584,744,

granted June 15, 1897, upon application of Ladd & McFeely. It is to be understood, however, that in its broader aspects and principles of operation the invention is of general application,

An object of this invention is to provide a Work support which, While giving the operator every facility for manipulating the Work freely and presenting it in any desired relation to the operating instrumentalities of the machine, will hold the Work fixedly during the operation of those instrumentalities upon the Workand relieve the operator coinp letely from the exertion and consequent fatigue of holdingthe Work to the machine during such operation. a

A feature of invention consists in a Work support organization including a Work holder on which the Work is held in predetermined position and which is fr'eelymovable to allow the operator, While holding the Work or Work holder in his hand, to .present the Wort to the operating instrunien talities of the machine in the natural and usual mannerto Which he is t-rainechand a supporting structure which may be rendered fixed at times to hold the Work while the said instrumentalities are performing an operation or operations upon it.

lVhen. as show-n, the ork holder is designed to hold a shoe and last, its movement preferably includes a rocking movement, that is, movement by which the shoe is positioned about a longituc'linal axis; tipping movement, that is, movement by Which the iih'oe is positioned about a transverse axis; rotative movement, that is, movement by which th'e'shoe is positioned about an axis perpendicular to the shoe bottom: and trans- 50 latory' movement, that is,n'1oven'1ent by which the shoe may be positioned by bodily movement vertically or horizontally.

The supporting structure, as shown, coinp'rises 'triangle-:liorming rods connecting points on the last holder wlth points on a rigidly supported base member. The rods are normally movable longitudinally through the last holder or base member, preferably the latter, and when held against movement in the base member form with the last holder and base member a structure composed of triangles Which is rigid against "deformation in any direction on the Welllrnoiyn principle that a triangle is the only geometrical figure the shape of which cannot be changed Without changing boththe length of the sides and the angles. The simplest form of such a structure is an octahedron. Accordingly, in the construction shown, three points on the last holder, forming the upper triangle, are connected to three points on the base member, forming the lower triangle, by three pairs of rods, each pair being arranged to connect one point of the last holder with tutopoints oi the base member, the six rods forming six side triangles which, with the upper and lower triangles, form an octahedral structure. M

A further feature of the invention consists in means for maintaining the upper triangle in the same relation to the lower triangle, so far as relative rotation in a hori- Zontal plane is concerned, and yet allowing rotation of both triangles togetherso that the last holder may have the rotative movement above mentioned. As shown herein, a base member, herein also termed anivheel me'mliier, is arranged for rotation substantia'lly in a horizontal plane, and there are connections between the last holder and the Wheel member so arranged that rotation of one compels rotation of the other, the upper and lower triangles being so arranged that the corners or the upper triangle are over the sides of the lower triangle.

A further feature of the invention consists in connections between the upper and lower triangles constructed and arrang ged to permit movement of the upper triangle to- Ward and from the lower triangle, tipping or inclination of the upper triangle relatively to the lower triangle in any direction, and a bodily horizontal movement of the upper triangle relatively to the lower triangle in any direction.

Another important feature of the invention consists in means for rendering theconnections between the upper and lower triangles fixed or substantially rigid Which, in

the construction shown, consists in means for locking the rods to the lower triangle or wheel member at their points of passage through it, the locking means being preferably operated in time relation to the operating instrumentalities of the machine in connection with which the work support is used.

Another feature of the invention consists in means for holding the support against rotation during the time it is held rigid against other movements. in the construction shown this is effected by locking'the wheel member against rotation. I

Another feature of the invention consists in a last holder comprising a heel pin and a forepart engaging member which are arranged for relative movement about a center located beneath the last to release the last, means for independently supporting the heel pin and forepart engaging member at times, and means for holding the center between the heel pin and the forepart engaging member from movement while said parts are independently supported to cause the last holder fixedly to hold the last.

Still another feature of the invention consists in a work support having three points of support whereby a structure rigid in all directions is provided. As shown, two

points of support are on the machine head and the third is arranged for vertical movement so that the support is adjustable with the head when the head is moved up or down to suit the height of different operators.

These and other features of the invention including various novel constructions and combinations of parts will appear more fully from the following description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

In the drawings, Fig. 1 represents, in side elevation, a work support or ack embodying the present invention applied to a machine having insti nncntalities for operating upon -a' shoe held upon the support. The instrumentalities with which the illustrated machine is provided comprise a work rest against which the bottom of the shoe is held, an edge rest l against which the side the shoe is pressed, a gripper 6 which is operated to tension progressively successive portions of the upper, a wiper 8 which is reciprocated to wipe the tensioned uppe against the bottom of the sole, and a driver 10 by which tacks are driven through the wiper 8 to secure the upper in lasted position.

The work support or jack includes a last holder which consists of a member 12 (Fig. 3) carrying a last pin 14 to engage the usual pin hole of the last and a forepart rest 16 which is pressed upwardly against the last to lift the forepart and cause the rear part to be cramped upon the pin 14 and held against ver tical movement. The heel pin member 12 and the forepart member 16 are pivoted together at 18 by a pin extending transversely of the shoe. in the member 16 isa bore 20 containing a spring 22 the upper end of which rests against the bottom of the bore 20 and the lower end of which is enclosed in a sleeve-like plunger 24 having a bottom which rests on a projection 26 of the member 12. The effect of the spring 22, therefore, is to cause the member 16 to turn on the pivot 18 toward the shoe and to cramp and hold the shoe on the pin 14. The pivot pin 18, besides forming an axis for relative movement of the parts 12. and 16, has a bearing in a block 28 on which both the parts 12 and 16, which, taken together, are herein termed the last holder, may turn together to eifect a tipping movement of the last. The block 28 extends upwardly, as shown by dotted lines in Fig. 1, between bifurcations of the member 12 in a position to engage a face 011 the member 16 when the last'holder is tipped on the axis 18 more thanis required in the normal operation of the machine. When this occurs movement of the member 16 is arrested while movement of the member axes of the pins 18 and 32, these three axes giving the last holder complete universality of movement substantially without translation.

It is necessary that the last holder have movements of translation both vertically and horizontally in all directions, not only to enable the shoe to be moved into and out of operative relation to themachine to enfill ward impulse of the driver .10.

ment possessed by the last holder combined 'Wltll its capacity tor movement of translation vertically and horizontallyenables the 'operatonwhile holding the shoe in his hands in the usual manner, to present any desired partoi the shoe to theoperating instrumentalities in the position required for the most advantageous action of those instrumentalities. It is further desirable to provide means for holding the shoe against movement in response to the action of the operating instrumentalities, particularly the outward thrust of the wiper 8 and the down In the coustr ction to be described the last holder is locked against movement in any direction whatsoever.

The entire work support, including the last holder, as described, is carried by a frame a which is secured to the head of the machine which has a neck telescoping in the upper end of the column as, the column being split and provided with a clamp screw 37 by whieh it may be clamped upon the neck Straps 44:, 436 (Fig. are secured by screws 38 one to each side thetrame 40. The straps extend obliquely upward and are. secured at their upper ends by screws 39 to the opposite ends or a yoke 48 which extends across behind the neck 36 to which it is securely clamped by a 'U-bolt 50. The screws 39 provide, therefore, two points of suspension for the frame 40. A third point oft support is provided for the frame 40 by an arm ell which, as shown, is integral with the frame and extends downwardly and around the column to the rear of the column where it has an ear l3 provided with a cylindrical hole that on gages. freely an enlargement on a screw 49 by which the neck 36 is adjusted vertically .in the column The screw is threaded through a portion 51 ot the column and has a conical end engaging a recess. in the lower end of the neck 36. By loosening the clamp screws 37 and tiu'ning the screw 4t?) the neck 36 and head 35 may be adjusted vertically to suit operators of difierent heights. Incidentally, of course, the frame 40 and the work support mechanism will be carried up or down with the head and the operative relation ofthe worlt support with the operating instrumentalities of the machine will remain unchanged. The

, three-point support of the frame 40 provides structure which. is rigid in. all directions and one which may be very readily attached to or removed from existing machines.

In the frame 40 is a circular rabbet 52 'rabbet 52 above the. ring ring member in which *1 her so.

containing a split ring 54:, the ends 56, 58 of which appear in Fig. 8. liitting intothe :i-l a circular is one half 01 a sail race, the'other half of which is formed in the periphery of a wheel-like base mem- The ring 60 is secured to the frame lllby screws (i i passing through lugs on the ring and threaded into the frame ll Balls 66 are inserted into the ball race by removing a screw-plug b8 and constitute a. ball bearing tor the wheeler base member 62 to permit, normally, tree rotation thereoi when the last holder is turned, connection being established between the tube 34, which, as

described, turns with the last holder, and

the wheel member 62 to cause them to turn together. F or this purpose the tube M carries between its ends two rolls 70 (Figs. 3 and 8) which are journaled on a pin passing through the tube and through a short plug which tills the tube at this point and provides a suitable support for the pin 72. The rolls T0 move up and down with the rod, the last holder is elevated and depressed, in a slot 'i t formed in a hub member To and in a reduced upper portion 77 t the inenioer, the rolls resting, when the U' l. holder is in its lowest position, upon r19, ines at is in Figs. 3 and 6. The slot 74 tops short or the upper end of the portion 2''? (Fig. 3) which is formed with an open ing to guide the tube 3%. The portion 77 isenclosed in a tube or casing 79 to exclude dust and dirt from the slotted portion and the rolls 70. lVhen the las holder is raised to present the work to the machine the rolls 70 will occupy a position somewhere in the reduced upper portion or stem 7'? oi the hub member 76. The hub member 76 is spherical and is seated in the center of the wheel member 62, being retained therein by a cap ring80 (Fig. 6) secured by screws L 1. Thus the hub 76 has a universal joint connection with the wheel member 62 which permits the stem 7'? ol the hub to assume various inclined positions relatively to the member (52 as the last holder is moved in and out or sidewise. The hub T6 turns with the tube 34 whenthat is rotated axially by reason of the rolls 70 engaging the slot- H in the stem 77 and the hub 76. To cause rotation oi the wheel member (32 with the hub 76, a. ball 82 is seated in a recess in the wheel member and engages a slot 81: "formed in the hub i6. Thus, the stem 77 and hub 76, while able to tip in any direction by reason of their ball and socket joint with the wheel mem her, have any movement of axial rotation transmitted to the wheel member through the ball 82.

To sustain the last holder periodically in any position given it by the operator, an octahedral structure is provided. Tine meanbottom of the slot indicated in dotted iug of the term octahedral as applied to this structure will be clear by comparing the geometrical figure 01 Fig. 7 with the struc ture to be described. In Fig. '1' a small up per triangle a, b, 0 is connected by six side triangles to a larger base triangle A, B, C. Obviously the position of the upper triangle a, b, 0 may be changed provided the sizes of at least three of the side triangles are changed. It the triangle a, b, c is moved bodily toward or from the base triangle A, B, C, the sizes-out all of the six side triangles will be changed. The upper triangle a, Z), 0 is represented in the structure herein shown by three points (Fi 2), one point being on the heel pin part 12 and the other two 92, 94 beingon the part 16 which is extended laterally suitably to space these points apart. At these points respectively rods 91, 95, 95 are connected by ball joints. As close as is practicable to the ball joints other rods 96, 98, are pivoted respectively to the rods 91, 9s, 95. The six rods 91, 95, 96, es, 100 are arranged to form the six side triangles of the octahedral structure.

The wheel or base member 62 has three spokes 102, 104, 106, each or which is cylindrically bored longitudinally and contains between its ends means for locking two of the rods as closely as is practicable at a single point. Taking, for example, the rods 95 and 98, these rods pass through the spoke 102 (Figs. 6 and 8) which has slots 110, 112 above and below to permit their passage, these slots being at an oblique angle to me length of the spokes because of the slanting direction at which the rods enter them. In the cylindrical bore of the spoke 102 are two cylindrical members 11 1, 116 which can rotate in the bore and move longitudinally of it. Extending transversely of the cylindrical member llt is a cylindrical locking member in two halves 118, 120. The rod 98 passes through a slot 122 in the member 11a parallel with its axis and wide enough freely toreceive the rod and through grooves one in each half 118, of the transverse locking member, the depth of the grooves being such that the halves 118, 120 can be pressed together to grip the rod before the flat sides of the halves come together. In the cylindrical member 116 is a transverse locking cylinder 124, 126' for the rod 95, the cylinder being constructed like the cylinder 118, 120. The adjacent halves 120, 124 of the two cylindrical locking members extend outside of thecylinders 11st, 116 respectively and engage each other as is shown in Fig. 6. Obviously then, if the cylinder 11a is held against movement longitudinally of the spoke 102 and pressure is applied to the outer end of the cylinder 116, both locking cylinders 118, 120 and 12 1, 126 will be jammed against the rods 98, 95 respectively and will lock them against longitudinal movement.

Also when such pressure is not applied the rods will be tree to move longitudinally and to assume any angle to the spoke 102 so far as permitted by the width of the slots 110, 112 (Fi 5). V In the spoke 104; similar locking mechanism is provided for the rods 91 and 100 and in the spoke 106 similar locking means for the rods 93, 96. The inner cylindrical members of these locking mechanisms, corresponding to the member 11 1 of the mechanism in the spoke 102, are designated by the numerals 113, 115 and have on their inner ends protuberances 130, 181 which bear against the hub member 7 6. When the members 113, 115 are forced inwardly they first engage, by their protuberances 130, 131, the hub member 76 to lock that against movement in any direction and then offer the necessary resistance to cause the rod locking mechanism in the spokes 10 1, 106 to operate.

The cylindrical member 114 has a protuberance 133 which, instead of engaging the hub 76, engages a movable member 136 (Fig.

6) arranged to slide radially of the hub 76 and having an outer surface corresponding to the spherical curvatureol' the surface of the hub. The member 136 has a protuberance 138 which is arranged to engage the 4 tube 3 1 and, upon inward pressure being applied to the member 136, to lock the tube 34: against longitudinal movement. To stiffen the tube against the lateral thrust'of the protuberance 138, the portion of the tube below the rolls 70 may be provided with a septum 1410 arranged with its edgesin line with the direction of movement of the protuberance. Of course, a solid core could be provided for the tube but the thin septum furnishes the required rigidity with less weight to be moved by the operator.

To apply to each of the three cylindrical members 116 inward pressure to efiect the locking of all the six rods and tube 3 1 against longitudinal movement, and the hub 76 and wheel member 62 against rotation, a

single means is employed, namely, the split ring 541 before mentionet. In the outer end 0t each of the cylindrical members 116 is an adjustable screw stud 1'12 held in adjusted position by a set nut 1 1 1. The stud is so adjusted that its outer end will just clear the ring 54 when the ends of the ring are separated. To prevent excessive outward movement of the members 116 screws 1 16 are threaded into the spokes near their outer ends and have conical portions which enter V-shaped grooves in the members 116 Fig. 4) The screws 1 16 are so adjusted and held by set nuts 148 that while limiting outward movement of the members 116 to prevent rubbing of the screws 1412 against the ring 54:, they will permit suflicient inward movement thereof to efiect locking of the parts messe as descriloed. effected hy niecha in best shown in Figs: 3 and S. The eiul 56 ot the split ring is held hy an adiustahle screw t!) which a su tahle notch inthe r. it. siuiilar untrh in the other endot the rino; is engaged hy a plun r at theproper ti action of the ring 5 1: is

Wardly projecting portio 158 carnving a rounded stud 1130 which engages the plunger In the inner end of :the lever 15a 3) isa bore con c sing a plunger 162 having a stern 164; .rhich e-ktends through a hole in the hot oil t,acap sleeveltitl which isthreaded into the hereof the lever. A spring 168 embraces thesten'i 164i and hears at oneend against the plunger 162 and at the other on the cap-sleeve 166. The plunger 162 i cupped to receivea hall 171 on an op era-ting rod 170, the ball losing retained by a hall cap 172threaded into} the bore of the 1ever'15 -l.

Obviously the construction described tords a yielding connection between the leverlii and the operating rod 170 by which the thrust of therod. is transmitted to the lever 15- and thence tothe locking plunger 15;, and the tension of the spring; 188 may he variedhy turning the sleeve 166.110 vary the force transmitted by the rodl'TO to the plunger 15-2, IDOVGZDGQtOf which will contract the ring andloeln theparts in the manner \lescrihed. The rod 170 'nay he con nected to any part .otthe ,niachine, in con nection with which. the Work support is used, \vl ieh operates intlie proper timerslation to the operating instrumentalitics to lock and unlo lcthe u'orl: support at thereqnired tiniesor, of course aspecial earn .011 the niachineshatt may he pro ided forthe purpose. as applied torthe hand inethod 255551111 iiuichine it is found that the rod 170 ,e conveniently connected to the usual ting; lever 180 (Fig. 2) which operates in the required time relationto the other operatineparts or" the-unachine. As shown the rod 170 hasa hall and socket connection 11182 with this lever 180. The end of the lever 180, to which therod 170 is connected, is moved downwardly to effect lock ing' of the Work support before the wiper 8 operates upon theswork and does IlOhllSE to release the ork support until the driver has; driven a tack. The shoe i l i 9 r, to the great relief of the operator, durthose portions of each cycle inavhich is appliedhy the machine tothe shoe an. to move it from the position flu which he has placed it and at other times in thee; cie the shoe is left free so that the opor niay nove it treelyat will and place ,the most advantageous position tor the opei [on oi the a acaine. "Will be seen that the operator, in holdtherefore,

,ingthe shoe up to the nachinghas to lift, lllstlfiltlllilol'llO the Weight oi theshoe, only theilastholder, the s12: rods and the tuhe 34;.

These parts lllitjfpllll he made verylight so light in i'act,that thefiehsl'ht which the operator has to lift inpaddition to the Weight of the SliOQ lS insignificant comparedto the great advantage gainedhy having the shoe securely held against displacement by the operating instruniientalities of the machine during theiroperation. The full locking pressure ot the split ring fitis applied inultaneously to all theloclzed parts, and since the locking is due to pressure on frictionally en gaging sur laces, the pressure may he so adjusted that the parts, W'hile held rigidly to withstand any normalst-resses put upon them, will slipfunder undue or abnorinal strains such as might be occasioned, for

example by theaccidental engagement of the positivelyroperated wiper 8 with the side of the shoeinstea d ofpassing overthe hottoni oi the shoe asjitis intended to do. Thus undue strain upon the parts or breakage of them is avoided.

When no Work is in the machine the rolls 70 will rest upon the bottom 78 ot the slot 7t and the support may he swung outwardly as far as permitted hythe engagement of the casing 79 in the extension 'T'Yoihthe hub member against the retaining ring 80, as will be clear tronrFig. 3. The portion oi the last holder may then be depressed, movement of the part 16 ofthe holder being liniited by engage nentot the face 25 with the block 28, the spring 22 being of course compressed. The last is then placed upon the pin 14, swung into position over the part 16, and the portion 12 released, whereupon the spring 22 will causethepart 16 to enease the forepart of the last and tip it to cramp the last uponthe pin 14. The operator then takes the shoe in his hands in the same way that he is accustomed to do, raises it against the bottom o'fthe rest and places the portion of the side of the shoe at which he desires to he in the operation againstthe edge rest 4;. [He thenstcps upon the treadle to start the machine which, in the case of the lasting machine shown. will cause the gripper 6 to seize a portion of the upper and tension it upwardlyand over the last, this action tending principally to lift the last against the support 2 Without tending to displace the last. Before the Wiper 8 begins to Wipe the upper over the last, however, the lever 180 is operated to close the split ring 5 1 and lock the parts of the Work support at the various points, as described, to hold the last holder firmly in position. The Wiper then operates to Wipe the upper into lasted position and the driver 10 operates to drive a tacic through the Wiper and into the last bottom. Innnediate ly after the tack is driven the lever 180 retill ' it is placed by the operator during the op leases the split ring and the last holder is then perfectly tree to allow the operator to present the work in a new position where the described operations will be repeated.
